This medication is given by injection into a muscle (upper arm or buttocks) by a health care professional. It is given as directed by your doctor, usually once every two weeks. To reduce irritation from the injection, your doctor will alternate between the left and right side with each dose.

When you first start this medication, it may take at least 3 weeks before this medication starts working. During this time, your doctor will instruct you to take another medication by mouth. Follow your doctor's instructions carefully.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

You should receive this medication regularly to get the most benefit from it. To help you remember, mark your calendar to keep track of when to receive the next dose. Keep receiving this medication even if you feel well.

Tell your doctor if your condition lasts or gets worse.
